作者利用阿波罗纽斯定理(Apollonius law)进一步探讨了一种新型的反射计技术。首先,确立了模拟六端口反射计的一般数学模型及其相应的电路模型。然后,着重分析了几种单位矢量形成网络,并利用广义反射计响应方程的端面不变性建立所需的数学模型。简略介绍了几种实用的模拟六端口反射计电路。最后,讨论了一种网络分析的简便方法。 The authors use Apollonius law to further explore a new type of reflectometer technology. First of all, the general mathematical model of analog six-port reflectometer and its corresponding circuit model are established. Then, several kinds of unit vector formation networks are emphatically analyzed, and the mathematic models are established by using the surface invariance of the generalized reflectometer response equation. Briefly introduced several practical analog six-port reflection meter circuit. Finally, a simple method of network analysis is discussed.
